Overview
This sub-programme gathers the condensed-matter applications of the Cosmochrony framework. Both rest on the same object — the Weil–Heisenberg substrate $\mathrm{Heis}_3(\mathbb{Z}/q\mathbb{Z})$ and its winding sector $w=2$ — but read two complementary regimes of it.
In the superconductivity paper, the stabilisation and condensation of the $w=2$ composite is the pairing mechanism: superconductivity is projective phase locking of that composite, with $d$-wave symmetry in cuprates and extended $s^\pm$ symmetry in nickelates following from real-space frustration minimisation. In the quantum Fisher information note, the same substrate is read in its uncondensed, fluctuating regime: the scale-free growth of the quantum Fisher information density measured in a strange metal is a property of the full nilpotent substrate, not of any single composite.
Constituent papers
- A Unified Real-Space Frustration Mechanism for Superconductivity (companion paper G). Superconductivity as projective phase locking of $w=2$ composites driven by real-space frustration minimisation and lattice symmetry constraints, predicting $d$-wave symmetry in cuprates and extended $s^\pm$ symmetry in nickelates, with falsifiable scaling, disorder, and pressure signatures. DOI 10.5281/zenodo.18718224.
- Quantum Fisher Information as a Spectral Entanglement Witness. Reduces the scale-free growth of the quantum Fisher information density measured in the strange metal $\mathrm{Ce}_3\mathrm{Pd}_{20}\mathrm{Si}_6$ to the projective spectral data, and shows it is a property of the full nilpotent substrate (edge spectral dimension $d_s\approx 4$, $f_Q(T)\sim T^{-1}$), marginal for the single $w=2$ sector, with a thermal closure derived from the heat-kernel response. DOI 10.5281/zenodo.21001565.
Position within Cosmochrony
The sub-programme imports the substrate and the winding sector $w=2$ from the O-series spectral admissibility sub-programme, the Born–Infeld bounded-flux constraint from the foundational papers, and the heat-kernel identification of the diffusion scale with inverse temperature from the spectral thermodynamics paper. The quantum Fisher information note also defines a new spectral entanglement witness, complementary to the entanglement sub-programme: the projection entropy bounds Bell–CHSH violations and the residual-rank entropy counts conjugate-pair entanglement, whereas the quantum Fisher information counts the multipartite correlation depth of the steady state, which grows as the projective stability gap closes.
